A full version app for Android, by Yury Grebenkin.

This application is intended to help you locate objects and people in a short range. It uses a technique based on the sound waves travel time from your device to the target and back. This allows you to distinguish between a nearby object and a faraway one.

It is a radar-like system that works by sending sound waves from your device and then receiving the waves that the targets have reflected.

It works the same way as a radar system, except that it uses sound waves instead of electromagnetic waves, which could be called a sonar.

This app is a tool that helps you detect a person’s presence or object. It is helpful in finding your way in a dark room or a crowded place, and it is ideal for people who want to find a friend or an object.
